摘要/Abstract

摘要： 研究了杉木、马尾松、建柏、柳杉和木荷人工林的抚育间伐对林分土壤肥力的影响.结果表明,杉木、马尾松、建柏、柳杉、木荷间伐后降低了林分的郁闭度.改变了林内的生境条件,促进了林下乡土植被的生长和繁衍,林下植被覆盖度、植被生物量和物种丰富度有了较大幅度的增加,间伐的强度越大.增加的幅度也越大.与不间伐林分相比,各间伐林分两年后土壤微生物数量增加、酶活性增强、土壤容重降低、总孔隙度和速效养分提高,土壤肥力得到了改善和提高.间伐后林分土壤肥力得到提高的实质在于:间伐后林下植被生物多样性的提高诱发了土壤微生物多样性和数量的提高,并由此而增强了土壤的生物活性,加速了土壤养分的循环.

Abstract: The influence of thinning on soil fertilities in artificial forests of Cunning hamia lanceolata,Pinus massoniana,Fokienia hodginsii,Cryptomeria fortunei and Schima superba were studied.Thinning after two years reduced crown density of plantation stands,improved habitat conditions in plantations,promoted growth of native vegetation under plantations,increased understory cover degree,biomass and species richness.The more the thinning intensity,the more the effects.Compar ing with no thinning plantation stands,the thinning plantation stands increased soil microbe quantities,strengthened soil enzyme activities,decreased bulk dens ity,enhanced soil total porosity degree and available nutrients,improved soil fe rtilities after two years.The mechanism that thinning improves soil fertility is that the increased understory biodiversity after thinning enhances the increasi ng of quantity and diversity of soil microbe,and therefore,strengthens bioactivi ty of soil,accelerates nutrient cycling of soil.
